WebA) K+ enters the guard cells and water follows passively, making the cells turgid. B) Loss of K+ from guard cells creates positive pressure and expands the guard cells. C) K+ … WebMay 14, 2024 · Even when no water is being absorbed, minerals enter freely - mostly through the root hairs. Minerals can enter against their concentration gradient; that is, by active transport. For example, plants can take up K + from the soil against a ten-thousand-fold concentration gradient; e.g., from as little as 10 µM in the soil to 100 mM in the cell.
